New research suggests time could hold the key to resolving mysteries of gravity, quantum mechanics, and other phenomena in ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

The result from CERN confirms expectations, but it's the first time gravity’s effect on the stuff has actually been tested. Reading time 3 minutes In the 95 years we’ve known about antimatter, ...

Two recent studies explore whether time can exist in quantum superposition and how gravity might affect its measurement. One proposes using advanced ion clocks to detect quantum states of time, while ...

A new study suggests that certain 'quantum collapse models'—which posit that wavefunction collapse happens spontaneously—could be tied to gravity, introducing a tiny intrinsic uncertainty in time ...

For the second time in as many months, images gathered by the Hubble Space Telescope (HST) are raising questions about the structures of time and gravity, and the fabric of space. Using two HST images ...

Levon Pogosian receives funding from the Natural Sciences and Engineering Research Council of Canada. Camille Bonvin receives funding from the European Research Council (ERC) under the European ...

The holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close we are, or it it's even possible. But we shouldn't ...
